Answer
Ear Functions
Outer Ear – To collect sound waves
and direct them into the ear canal
Middle Ear bones – to act as levers
to increase the size of vibrations
Inner Ear – to convert vibrations into
electrical signals for the brain to
interpret
DiD you know…?
The semi-circular
canals are located in
the inner ear, but they
do not contribute to
the hearing process.
The canals help you
keep your balance by
allowing you to
determine which way
is up.
